"Air filter" is a kind of equipment that collects dust in gas-solid two-phase flow through the action of porous filter material, so that the gas can be purified.
“Air filter"It is through the relatively low dust content of the air purification treatment and then sent into the room, used to ensure the process requirements of the clean room and the cleanliness of the air in the air-conditioned room in general.
Among them, the "air filter", the pressure reducing valve and the oil mist device are called pneumatic three pieces. In general, in order to get more functionality:
These three kinds of gas source processing components are usually assembled together in sequence, so they are called pneumatic triples. Pneumatic triples are usually used to purify, filter, decompress and provide lubrication. Under normal circumstances, the installation sequence of the three major pneumatic parts is according to the intake direction.Air filterPressure reducing valve, oil mist device. Most of the pneumatic system in the indispensable air source device is pneumatic three big parts, it will be installed in the gas equipment near, is the last and most powerful guarantee of compressed air quality, "air filter" design and installation, but also need to take into account the saving space, easy operation and installation and so on.
Air filters are divided into coarse-efficiency filters, medium-efficiency filters and high-efficiency filters.
Among them, the filter media used for the coarse effect filter is generally a non-woven fabric, a wire mesh, a glass filament, a nylon mesh, or the like. The most common coarse filters are: ZJK-1 type automatic winding herringbone air filter, CW type air filter, etc. The structure of the coarse filter is plate type, folding type, belt type and winding type.
Common in-effect filters are: IV type foam plastic filter, YB type glass fiber filter, etc. At present, the filter material used in the medium effect filter is mainly glass fiber, polyethylene foam plastic and synthetic fiber felt made of polyester, polypropylene, acrylic and so on. Now the popular high-efficiency filters on the market are GB type and GWB type.
At present, the filter materials used in high efficiency filters are mostly ultra-fine glass fiber filter paper. Since the high-efficiency filter uses a very low filtration rate, the screening effect and diffusion effect on small dust particles are enhanced, so the high-efficiency filter has a high filtration efficiency.
